"When you go from being a relative unknown to being a success overnight, you definitely grow in leaps and bounds," says Rachelle LeFevre, who plays evil vampire Victoria in Twilight and the upcoming sequel New Moon. "The thing that was most striking for me was the way in which they didn't change."

One is the daughter of Hollywood royalty, and won a Golden Globe nomination for a 2006 performance in a Shakespeare adaptation. The other is a bilingual Canuck who likes an active role – and loves vampire books. But only one of the two – Bryce Dallas Howard, or the woman she's replacing in the Twilight series' Eclipse, Rachelle Lefevre – can play evil bloodsucker Victoria. Who do you think it should be?

Twilight fans weren't the only ones surprised by the news that Bryce Dallas Howard was replacing Rachelle Lefevre on the third film Eclipse.

"I was stunned," says Lefevre in a statement. "I was fully committed to the Twilight saga."

Lefevre, who played villain Victoria in the first Summit Entertainment-produced film and its upcoming sequel New Moon, said she turned down "several other film opportunities" and accepted only roles with short shooting schedules to make time for Eclipse.
